Water resources of the Umatilla Indian Reservation, Oregon
Joseph B. Gonthier, D.D. Harris
1977, Water-Resources Investigations Report 77-3
Water resources of the Umatilla Indian Reservation are poorly distributed both geographically and in time. On the reservation, only the Umatilla River and one of its principal tributaries, Meacham Creek, have significant perennial flows. Runoff of the principal streams is largely from snowmelt in the Blue Mountains and is highly...

The Sonoma Volcanics are the principal water-bearing materials in the lower Milliken-Sarco-Tulucay Creeks area, which occupies about 15 square miles (39 square kilometers) in and east of Napa, Calif. The distribution and composition of these volcanic units are highly variable and complex. Within the Sonoma Volcanics the tuffs constitute the...
Ground-water quality near a sewage-sludge recycling site and a landfill near Denver, Colorado
Stanley G. Robson
1977, Water-Resources Investigations Report 76-132
The Metropolitan Denver Sewage Disposal District and the City and County of Denver operate a sewage-sludge recycling site and a landfill in an area about 15 miles (24 kilometers) east of Denver. The assessment of the effects of these facilities on the ground-water system included determining the direction of ground-water...

1977, Open-File Report 77-492
The part of the Arctic coast of Alaska between the Colville River and the Canadian boundary was visited in April, August, and November 1975. The study area is characterized by its cold climate and is largely uninhabited, but oil and gas discoveries have spurred development of parts of the area....
Estimating the magnitude and frequency of floods on natural-flow streams in Massachusetts
S. William Wandle Jr.
1977, Water-Resources Investigations Report 77-39
The magnitude and frequency of floods on natural-flow streams in Massachusetts, with drainage areas between 0.25 square mile and 497 square miles, may be estimated from drainage area, main channel slope, a precipitation index, and a storage factor. Multiple-regression techniques were used to define the relationship between basin and climatic...
Geology of the Midnite uranium mine area, Washington — Maps, description, and interpretation
J. Thomas Nash
1977, Open-File Report 77-592
Bedrock geology of about 12 km2 near the Midnite mine has been mapped at the surface, in mine exposures, and from drilling, at scales from 1:600 to 1:12,000 and is presented here at 1:12,000 to provide description of the setting of uranium deposits. Oldest rocks in the area are metapelitic...
Reconnaissance of ground-water resources in the Mountain Home plateau area, southwest Idaho
H.W. Young
1977, Water-Resources Investigations Report 77-108
The Mountain Home plateau area occupies approximately 1,220 square miles of the western Snake River Plain in southwestern Idaho. About 40,000 acres are presently (1977) irrigated with ground water, about 30,000 acres with surface water. An estimated 450,000 acres are potentially irrigable, if water is available. Development of ground-water re-sources...

1977, Geology (5) 557-562
Ribbon cherts and siliceous tuffs of the North Fork and Rattlesnake Creek terranes of the Klamath Mountains yield Mesozoic radiolarians. Rocks of the North Fork terrane were previously considered to be of Paleozoic age and those of the Rattlesnake Creek to be of Paleozoic and Triassic age, on the basis...
Deposition of the Tapeats Sandstone (Cambrian) in central Arizona
Richard Hereford
1977, GSA Bulletin (88) 199-211
Grain size, bedding thickness, dispersion of cross-stratification azimuths, and assemblages of sedimentary structures and trace fossils vary across central Arizona; they form the basis for recognizing six facies (A through F) in the Tapeats Sandstone. Five of these (A through E), present in western central Arizona, are marine deposits containing...

Richard Z. Poore, William V. Sliter, M. H. Link
1977, Journal of Research of the U.S. Geological Survey (5) 735-745
Lower Tertiary strata in .the northern Santa Lucia Range of California are correlated by means of planktonic and benthonic foraminifers. Benthonic foraminiferal assemblages from eight stratigraphic sections range in age from Ynezian to possible basal Refugian. The Paleocene mudstone contains a Ynezian benthonic foraminiferal assemblage. The Ulatisian benthonic assemblage of...

1977, Journal of Research of the U.S. Geological Survey (5) 761-781
The terrane bordering the alpine-type Josephine Peridotite on the north in the Vulcan Peak area, southwestern Oregon, is composed of intrusive hornblende gabbro (Middle Jurassic) and scattered remnants of clinopyroxene-bearing ultramafic rocks and amphibolite. The amphibolite, which preliminary analyses suggest is of andesitic composition, has undergone regional metamorphism to the...
A Galerkin, finite-element analysis of steady-state flow and heat transport in the shallow hydrothermal system in the East Mesa area, Imperial Valley, California
R.E. Miller
1977, Journal of Research of the U.S. Geological Survey (5) 497-509
A steady-state simulation model was applied to the shallow hydrothermal system in the East Mesa area of Imperial Valley, Calif. The steady-state equations of flow and heat transport were solved by use of a Galerkin, finite-element method. A solution was obtained by iterating between the temperature and pressure equations, using...
